The service area is the same as that provided with NTT DoCoMo's Xi (crossy) and FOMA services. To use the service in Xi (crossy) areas you will need a LTE-compatible device.

Speeds / Supported Areasarrow

With the 7 Giga Plan, until the monthly 7GB limit of data traffic reaches about 7GB the service can be used at a maximum speed of 262.5Mbps. Should the 7GB limit be reached in a month, the connection speed will be reduced to 200Kbps until 00:00 on the first day of the following month.

With the 3 Giga Plan, until the monthly 3GB limit of data traffic reaches about 3GB the service can be used at a maximum speed of 262.5Mbps. Should the 3GB limit be reached in a month, the connection speed will be reduced to 200Kbps until 00:00 on the first day of the following month.
